Abstract
Die Erfindung betrifft ein Verfahren zur zur Ermittlung einer benötigten Fahrzeit eines Zuges beim Zurücklegen einer Strecke mit vorgegebener Neigung und zulässiger Höchstgeschwindigkeit.The invention relates to a method for determining a required travel time of a train when covering a route with a given inclination and maximum permissible speed.
Erfindungsgemäß wird eine einer Beschleunigungsphase zugrundeliegende Differentialgleichung v'(t) = a v2(t) + b v(t) + c mit einer von einer Zeit t abhängigen Geschwindigkeit v(t) und Parametern a, b, c durch geschlossene Formeln gelöst und diese geschlossenen Formeln neben den allgemein bekannten Rechenvorschriften für Zugfahrten mit konstanter Geschwindigkeit bzw. konstanter Bremsverzögerung benutzt werden, um wie folgt die Fahrzeit zu ermitteln:
- bei positiver Beschleunigung v'(t) > 0 wird geprüft, ob ausreichend Strecke zur Erreichung der Höchstgeschwindigkeit zur Verfügung steht und wenn genügend Strecke zur Verfügung steht, wird die Zeit und der Weg, die für die Beschleunigungsphase erforderlich sind, durch geschlossene Formeln ausgedrückt und mit konstanter Höchstgeschwindigkeit weitergefahren sowie werden andernfalls die geschlossenen Formeln für die Zeit und den Weg, um auf eine bestimmte Geschwindigkeit zu kommen, dafür genutzt, um durch ein numerisches Verfahren, insbesondere dem Newton-Verfahren, die Austrittsgeschwindigkeit und -zeit aus dem Streckenabschnitt zu bestimmen,
- bei negativer Beschleunigung v'(t) < 0 wird geprüft, ob der Zug evtl. vorher zum Stehen kommt, gegebenenfalls wird der Zeitpunkt des Stillstands und die dabei zurückgelegte Strecke ermittelt, ansonsten wird die Austrittsgeschwindigkeit sowie die benötigte Fahrzeit durch die geschlossenen Formeln ermittelt,
- bei Beharrungsfahrt v'(t) = 0 wird eine Einbruchsgeschwindigkeit V0 beibehalten,
- grundsätzlich wird eine evtl. vorgegebene Begrenzung einer Austrittsgeschwindigkeiten durch einen rechtzeitig eingeleiteten Bremsvorgang berücksichtigt.According to the invention, a differential equation v '(t) = av 2 (t) + bv (t) + c underlying an acceleration phase is solved by closed formulas with a speed v (t) dependent on a time t and parameters a, b, c closed formulas are used in addition to the well-known calculation rules for train movements with constant speed or constant braking deceleration, to determine the travel time as follows:
in the case of positive acceleration v '(t)> 0, it is checked whether there is enough distance to reach the maximum speed and if there is enough distance, the time and the distance required for the acceleration phase are expressed by closed formulas and continue at a constant top speed, and otherwise the closed formulas for the time and the way to get to a certain speed will be used to, by a numerical method, in particular the Newton's method, the exit speed and time from the section determine,
- If the acceleration is negative v '(t) <0, it is checked whether the train may come to a stop beforehand; if necessary, the time of the standstill and the distance traveled are determined, otherwise the exit speed and the required travel time are determined by the closed formulas .
in steady-state travel v '(t) = 0, a break-in velocity V 0 is maintained,
- In principle, a possibly predetermined limitation of a discharge speeds is taken into account by a timely initiated braking process.
